Abstract

Patent contains meaningful technical achievement. There are many cases explaining technology trends from the analysis of frequency of term. Term sometimes has different meaning on fields. In this paper, words from patent titles of US, Japan, Korea PCT and EPO are collected by the 5 categories of WIPO. Frequency changes rate of each word were calculated and high ranked words of 5 categories were analyzed to find relationship between patent and technology development as well as technology trends.

특허는 중요한 과학기술 연구 성과물을 담고 있다. 과학기술용어의 사용 빈도를 활용해 기술동향을 분석하는 연구가 있으나 용어는 종종 분야에 따라 다른 의미로 사용된다. 이 논문에서는 2000년부터 2008년 까지 매 2년 주기의 미국, 일본, 한국, 유럽(EPO), 국제(PCT) 특허의 제목(발명의명칭)으로부터 단어를 추출하여 WIPO가 제시한 전기공학, 기기, 화학, 기계공학, 기타 등의 5가지 분류로 정리하여 용어의 출현빈도 변화를 계산하였다. 이 값이 상위에 있는 단어들을 분석하여 기술동향, 특허와 기술개발과의 관련성을 분석하였다.
